and there was a local guy who took one shot to the head and died in a coma. i've smashed boards that are harder than ribs- it's really not hard to semi-permanently maim someone in a couple of seconds if you know what you're doing...i hate to be the one to tell you, but MMA's not real.
euuuungh. allright, once more. the legs don't provide turning motion. it's pretty straightforward. they compensate and allow it, but the driving motion is at that central powerhouse. if your footing's nice and wide, you don't need to step, but there's disadvantages to that, too.
